I was a little surprised about the lack of discussion for a Python runtime.

What does it take to create a generic runtime, and what does that mean exactly?

It seems like you'd still have to have a graphics library backing the initial implementation, so I'm assuming that this is why Corona was used with Lua, for instance? Are you just making sure that the implementation is sufficiently discrete to allow plugging the non-drawing pieces into a graphics library of your choosing?

I'm interested in looking into a Pygame runtime, but I'm not sure where to start, or what it entails.

I'd be happy to contribute the resulting work.

Is there a quick and dirty explanation of the bits and bobs that make up the runtime, and how to go about creating one from scratch?

Anyone else interested in a Python runtime?
